Single-photon sources are key building blocks for future applications in quantum information, communication, cryptography and computation. The most important characteristics for single-photon sources are the brightness, the purity of single-photon emission and the indistinguishability of the emitted photons. Directly accessing the number of detected photons via transition-edge sensors, it is theoretically possible to reduce the number of required measurements to obtain these properties and to improve their statistical certainty.
In this work, we analyze deterministically fabricated single-photon sources by means of HBT and HOM experiments exploiting PNR detectors and compare the results with those obtained with Silicon-based click-detectors. Furthermore, we demonstrate statistical methods to evaluate the data obtained from experiments using PNR detectors and to extract key parameters, such as the g(2)(0) value and the two-photon interference visibility. Our analysis demonstrates, that PNR detectors can be used for the metrology of solid-state based quantum-light sources.
